Equipment information:

The PM5139 function generator introduces a new concept of
menu-driven operation to waveform generation and frequency
synthesis.
Microprocessor control enables simple and rapid operation
and allows you to set parameters by stepping through the
menu offered. One single control rotary knob allows you to
make precise settings of all numeric values.
The large backlit LCD clearly displays the selected signal
and gives a readout of vital parameters, such as frequency,
waveform, amplitude, and modulation. Any invalid parameter
selections are ignored and an error message shows the
incorrect settings that have been made.
The PM5139 frequency range covers IT/2 decades, from 0.1 mHz
to 20 MHz. Ten waveforms are selectable, including standard
functions, such as sine, triangle, square, as well as
positive and negative sawtooth, different pulses, and haversine.
Seven modulation modes are available:
• Amplitude modulation (AM)
• Frequency modulation (FM)
• Phase Shift Keying (PSK)
• GATE
The 10-key section on the right of the front panel permits a
versatile activation and control of such functions as single
or continuous sweep or burst, sweep hold, and switching from
internal to external modulation or trigger source; further
asymmetrical waveforms with variable duty cycle, key for
instant return to symmetrical waveform, store and recall
keys for up to nine complete instrument settings, a DIAL
LOCK key to disable the rotary control, and a key for
switching the signal output impedance.
AC or DC amplitudes can be precisely set using the numeric
setting rotary knob. DC offset is set independently of the
AC output amplitude. The output signals phase noise and
residual FM are very low, ensuring a clean and stable signal.
The instrument is optionally available under type number
PM5139/02 with a built-in GPIB (IEEE bus) interface and
under number PM5139/03 with built-in RS-232 interface. All
instrument functions can be remotely activated from a PC or
test system controller. It is also possible to upload
settings and status data from the instrument for storage in
the controller and later recall at any time. The facility
IEEE bus makes PM5139 an integral part of an automated test
system.
The PM5139 with interface also offers a user-definable
’’arbitrary” waveform ARB: the desired waveform may be
programmed on the PC, and than downloaded to the generator
via interface. Twenty-four arbitrary waveforms can be stored
separately.
A test program is built in to provide customer support and
to facilitate servicing.
The PM5139 is very much suited for applications in research
and development, production monitoring, quality assurance,
and for service purposes.
